Abstract (en)
[origin: WO2009107155A1] A DSSS detector (19) for detecting a synchronization between an aperiodic spread spectrum signal (r(nTc)) having a plurality of chips (r(n) ) and a spreading sequence (PN) having a plurality of chips (pi). The DSSS detector (19) has at least one branch (16) adapted to receive the spread spectrum signal, and the branch is formed by a plurality of correlators (1) cascade connected to each other and separated one another by a branch delay block (20). Each correlator (1) has a multiplier (12) for correlating chips (pi) of the spreading sequence (PN) with chips (r(n) ) of the spread spectrum signal (r(nTc)) and generating each an own correlation value (y(n)). The DSSS detector (19) further has a matching detector (22, 23, 27) receiving the correlation values (y(n) ) and detecting when all the correlation values (y(n)) are maximum.
